CONVEYING APPARATUS.

Application filed May 8, 1919, Serial No. 295,575. Renewed October 2, 1922. Serial No.1591,972.

T 0 all to ham it may concern.

Be it known that 1, Bacon V. Enwanns, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Conveying Apparatus, of which the following is a specification.

This invention relates to a turning conveyor which is more particularly designed for taking articles or loads of material which are being transported in one direction by one conveyor and turning the same preparatory to delivering the same to one or another of a plurality of other conveyors which are moving in different directions relatively to each other and thereby permit of distributing freight or similar material from one point where the same is loaded to differently located unloading points and places. Such turning conveyors are particularly useful in freight stat1ons, and similar places, where a large amount of miscellaneous freight is distributed and which must be assorted either according to the character of the freight, its destination or the manner in which the same is to be shipped.

It is the object of this invention to provide a turning conveyor capable of accomplishing this purpose which is universal in its operation so as to permita load to be transferred from a receiving line to a delivery line located at any angle with reference to each other and to accomplish this purpose by means which are comparatively simple in construction, efficient in operation, not liable to get out of order and capable of being operated by a minimum expenditure of power.

In the accompanying drawings:

Figure 1 is a diagrammatic top plan view of aturning conveyor embodying a practical form of my invention showing parts broken away for showing the internal mechanism. Figure 2 is a. fragmentary vertical section taken on line 2- 2, Fig. 1. Figure .3 is a fragmentary vertical section, on an enlarged scale, taken on line 3-3, Figs. 1

and 4. Figure 4 is a vertical section taken on line 44, Fig. 3.

Similar characters of reference refer to like parts throughout the several views.

The main frame of this turning conveyor is preferably constructed principally in the form of a rectangular box or hollow body l the horizontal top 2 of which forms the. platform or table of the turning conveyor. In this platform are arranged a plurality of openings 3 which are preferably circular and the openings in one row being arranged midway between the openings in an adjacent-row so that the several openings are of the platform and the several turret plates are practically continuous.

Pro ecting downwardly from the under side of each of the turret plates on opposite sides of its center are two upright arms 5 which are connected at their lower ends by means of a cross piece 6. The latter together with these arms forms a yoke andconstitutes with the top plate a aturret which is preferably formed integrally of cast metal. The lower end of this turret rests upon an upper horizontal web 7 arranged within the box of the main frame and forming part of the latter. Each of these turrets may be pivoted in any suitable mannerbut in the present instance this is accomplished by means of an upright shaft 8 which is journaled with its upper part within a vertical bearing 9 arranged concentrically on'the,

cross bar on. the turret, while the lower part of. this shaft is journaled in a vertical bearing 10 arranged on the web 7 and its lower parts rest against an abutment formed on a lower horizontal web 11 which is arranged within the supporting box and forms part of the main frame, as best shown in Figs. 2, 3 and 4. I

.The top plate of each turret is .provided with one orv more openings or slots 12, preferably two, which are arranged on oppo site sides of its axis and through'these slots two supporting or conveying rollers 13 project so that the tops of these rollers are arranged slightly above the level of the turret plates and the conveyor platform, the lower parts of these rollers being arranged between the arms of the respective turret, as shown in Fig. 4. Themembers of each pair of these supporting rollers are arranged axially in line andsecured to a horizontal driven shaft 14 which latter is journaled at its opposite ends in bearings 15 formed on the upper ends of the turret arms. Power is applied to the horizontal shaft and the supporting rollers connected therewith so that upon placing a box or other load upon these rollers the latter by their turning movement will cause the load to be propelled in a direction parallel with the plane of rotation of the supporting rollers. The means for rotating these supporting rollers may be varied as to details of construction but this is preferably accomplished by means which comprise a driving bevel gear 16 secured to the upper end the driving shaft 8 and meshing with a driven bevel gear 17 secured to the horizontal driven shaft 1aas shown in Figs. 2, 3 and l. The vertical shafts 8 of one row of turrets are preferably operated in pnison by means which include a horizontal distributing shaft 18 journaled in suitable bearings on the main frame between the upper and lower webs '7 and 11 and provided with a plurality of driving spiral gear wheels 19 each of which meshes with a driven spiral gear wheel 20 secured on the lower end of one of the vertical turret shafts between the opposing upper side of the lowe web and the underside of the upper web.

Although power may be transmitted to the several distributing shafts in any s. able way and from any suitable sou power in the present instance, is pr derived from a main driving shaft 2 is journaled horizontally in an enter on the underside of the body of the ii, The means which are preferably employed for transmitting motion from this driving shaft to the several. distrioutin shafts comprise a horizontal counter sl 23 journaled in the lower part of the f e box and at right angles to the distributing shafts and provided with a plurality of d 'v in'g spiral gear wheels 2% each of which meshes with a driven spiral gear wheel 27 on one of the distributing shafts. an inclined intermediate shaft 26 journaled in suitable hearings on the main frame, a pair of intermeshing

beveled gear wheels

27, 28 connected respectively with the upper end of the inclined shaft and the adjacent p; .t of the counter shaft 23 and a pair of intermeshing spiral gear wheels 29. 30 connected respectively with the main driving shaft and the inclined schaft, as shown in Fig. 2. This driving mechanism operates to transmit power from the main d1 ring shaft to the pairs of supporting rollers on the turrets so that these rollers turn sinniltane ously at the same rate of speed. and i'llQlGfOlU operate to uniformly transport a load resting on the same.

In order to prevent any article or load which is being pushed over these rollers from accidentally striking the side of the same and injuring them, in the event that the line of approach is at an angle to the side of the rollers, the top plate of each turret is provided adjacent to the outer sides of the supporting rollers with inclined fenders or guiding projections 31 which extend from the upper side of each supporting plate to the top of the supporting rollers as best shown in Fig. 4,, thereby causing the object which strikes these guides to be deflected to the top of the supporting roller end and avoid injuring the latter by a side blow.

in order to cause the article or freight to be turned from one line of movement in one direction to another line of movement in another direction all of the several turrets are operatively connected so that they will be turned in unison by an adjusting mechawhich may be operated either by power or otherwise. For this purpose each of the turrets is provided on its lower part with a driven gear wheel 32 and a plurality of intermediate driving gear wheels 33 are provided each of which meshes on its opposite sides with the driven gear wheels of adjacent turrets so as to cause all of the turrets to turn simultaneously in one direction or the other in unison. The axes of the horizontal shafts ll and supporting rollers are always parallel with each other in the various positions in which the turrets may be turned. one of these intermediate driving gear wheels 33., preferably one. arranged in the central part of the group, may be taken as the master gear wheel, and this wheel is secured to the upper end of a main or m-aster adjusting shaft 34 which is journaled in an ngia'ight position in suitable hearings on the main frame. This master shaft may be turned by any suitable means for shifting the turrets into the desired position and causing the supporting rollers thereon to be :21 angcd at the desired angle for shifting the freight resting thereon from one direction line to another. The means showni'n the drawings for adjusting the several turrets are organized that they are operated by power and controlled by an electrical clutch, which means. as shown in Fig. 2 are preferably constructed as follows:

represents a lower clutch shaft journaled in suitable hearings in the lower part of the main frame vertically in line with the master shaft and rotated continuously by means of a bevel gear wheel 36 secured to the inclined shaft 26 and mesl'iing with a bevel. gear wheel on the clutch shaft 35. On. its upper end the clutch shaft is provided with a driving clutch disk 38 the upper side of which is provided with a plurality of clutch jaws or teeth 39 arranged in the annular row. 40 represents a driven clutch disk mounted on the lower end of tne master shaft 3% by means of a spline so as to be capable of sliding vertically thereon but compelled. to tu'rn therewith. On its underside this driven clutch disk is provided with an annular row of clutchteeth 41 which are adapted to engage with the teeth of the driving clutch disk when lowering the driven disk or to be uncoupled therefrom when raising the driven disk. This raising and lowering of the upper driven diskmay be effected by a variety of means, for instance by a shifting ring 42- engaging loosely with an annular groove in the hub of the driven clutch disk, a pair of toggle links 43, 44 which have their opposing ends pivotally connected with each other while the outer end of one link is connected with the adjacent part of the frame and the outer end of the other link is connected with the clutch ring, a yoke 45 having a vertical slot which receives a pin 46 on the yoke, and two

solenoid cores

48, 49 which are arranged respectivelywithin the

coils

50, 51 of two solenoid electro magnets. Upon passing a current of electricity through coil 51 so as to energize the samethe core 49 therein will be drawn lengthwise in one direction and cause the toggle links to straighten and move the driven clutch disk toward the lower clutch diskso as to couple the clutch shaft with the master shaft while upon energizing the other'coil 50 the core 48 and associated parts willbe moved in the opposite direction and the clutch will be uncoupled. Suitable means for thus alternately directing the electric current from a source ofsupply 52 to either oneof the coils are shownin Fig. 2 and comprises a double switch 53 the movable members of which are connectedwith the terminals of the electric source and are adapted to be engaged either with a pairof contacts 54, 55 forming the terminals of one coil or with a pair-of

contacts

60, 61 forming the terminals of the other coil.

By this means the operator upon closing the switch through the proper coil can turn the central turrets until they have been adjusted-to the desired position and then dis-' connect the shifting mechanism from these turrets so that the latter remain in the ad justed position. While the turrets are in one position the freight delivered upon the several supporting wheels from one line of approach will be turned and discharged in a difierentdirection-along another line of.

movement in accordance with the predetermined wish of the operator. I As shownin thedr'awings the platform is of rectangular form and the turning mechanism is so organized that freightimatter canbe taken on at any one of its four sides and delivered at one or another of the remaining.

three sides by simply adjusting the several turrets so that the supporting wheels thereof are arranged at the proper angle to propel the freight,- from one line to another.

Forinstance, .if the, freight is'sup'pliedby a v carrier whichapproaches on that sideofthe turning conveyor indicated by the arrow 58 in Fig. 1, and the turrets are. arranged-in the position in this figure solthatthe axes of the supporting rollers are arranged at right angles to the supply line, then the freight will simply continue in :its move-.

ment across the platform of the turning conveyor and be delivered inthe same direc-- tion from the opposite side of the platform indicated by the arrow 59 in Fig. 1; If however, it is desired to transfer thefreight from the line of approach indicated by the arrow 58 to either one of the lateral sides of the platform indicated by arrows 56, \57 in Fig. 1, then the several turrets are ad justed so that theaxes of the supporting rollers are all arranged parallelfwith, the. line of approach and at right angles to the freight onto the platform and thedischarge therefrom on all sides thereof, each of the several sides of the platform is provided with a transfer bridge 62 upon which are mounted several anti-friction rollers 63 which are arranged cross wise of the particular line of travel and thus facilitate the move ment of any freight which may be deposited upon the same. f This turning conveyor is capable of being operated automatically from a distance by arranging the controlling mechanism adjathe freight is located, thereby, permitting freight tobe discharged to remote points from the place where it is loadedon to the conveyor without requiring any manual work for this purpose or the assistanceof' any additional attendants, therebyrendering it possible to distribute freight much more economically and rapidly than has been pos-,

sible heretofore. g
